How can we listen to the sound to find out why the brakes sound abnormally
1, the new brake pad abnormal sound
When the new car steps on the brake, there is a sharp piercing sound, many owners think that the quality of the vehicle must be a problem. In fact, the new brake pad and brake disc need a running-in process, when stepping on the brake, happens to grind the brake pad hard point (brake pad material caused by), will issue this abnormal sound, which is completely normal phenomenon,do not worry.
2. Make a muffled sound when stepping on the brake
This situation is mostly the fault of the brake caliper, such as movable pin wear, spring off, etc., will lead to the brake caliper can not work properly.
3, the sound of thrum thrum
This is probably the sound of ABS working normally. The ABS system will make the vehicle always in the critical gap rolling state, so when you step on the brake sharply to cause ABS to work, it will make a thumping sound. This abnormal sound is a normal phenomenon.
4,There was a slight sound when the brakes were pressed
General calipers, brake disc, brake pad faults are likely to produce this sound. If the sound is continuous, first check there is no drag brake, caliper reset will lead to disc and disc friction for a long time, under certain conditions will give out abnormal sound. If the new film is just installed on the abnormal sound may be new film and friction block size is not consistent caused.
